Abstract
It has been difficult to realize a connector device, and an electronic device and a plug using the same which can improve the reliability of connection sufficiently for practical use. In a connector device having a second connector half provided with a protrusion which falls into an engaging groove of a first connector half, an erroneous fitting preventing portion is formed in the first connector half so as to be deformed or broken by the protrusion of the second connector half when the first and second connector halves are erroneously fitted. Also, in a connector device composed of a plug and a socket into which the plug is fitted, uneven portions are formed on engaging surfaces with the plug and/or on engaging surfaces with the socket. Further, in an electronic device having at least one of a plug and a socket of the connector device, uneven portions are formed on engaging surfaces of the plug with the socket and/or on engaging surfaces of the socket with the plug.
Description
- 1. Field of the Invention
- This invention relates to a connector device, and an electronic device and a plug using the same, and more particularly, suitably applied to a connector device which prevents erroneous insertion, and an electronic device and a plug using the same.
- 2. Description of the Related Art
- In an electronic device such as a video camera, a power supply, a variety of data and so on are inputted from an external power source, various data sources and so on through a connection cable or the like. The video camera is connected to the connection cable by fitting a plug of a connector device, which is a male side connection terminal of the connection cable, into a socket of the connector device, which is a female side connection terminal of the video camera, in a predetermined state.
- In this way, the power supply, variety of data and so on are inputted to the video camera from the power source, various data sources and so on.
- However, since the connector device as mentioned above has been reduced in size, it is highly likely to reversely fit the plug into the socket instead of correctly fitting them or to obliquely insert the plug into the socket, causing a problem that these socket and plug are deformed or broken due to such mis-engagement.
- In such a case, both the socket and the plug are susceptible to breakage. However, a broken plug on the connection cable side may be fixed by replacing it with a spare part for repair, whereas a broken socket on the video camera side encounters difficulties in repairing only the socket since the socket is integrated (set up) in the video camera. Thus, the video camera itself cannot be used when the socket is repaired. In addition, this also causes an increased cost.
- In view of the foregoing, an object of this invention is to provide a connector device which is capable of improving the reliability of connection sufficiently for practical use, and an electronic device and a plug using the same.
- The foregoing object and other objets of the invention have been achieved by the provision of a connector device having a first connector half with an engaging groove and a second connector half provided with a protrusion which falls into the engaging groove when the first connector half is fitted into thereinto. In the connector device, an erroneous fitting preventing portion is formed in the first connector half so as to be deformed or broken by the protrusion of the second connector half when the first and second connector halves are erroneously fitted.
- As a result, this connector device can obviate the socket provided in an electronic device such as a video camera, from being broken by deforming or breaking the erroneous fitting preventing portion of the first connector half.
- Also, in the present invention, a connector device has a plug and a socket for receiving the plug, wherein uneven portions are formed on engaging surfaces of the plug with the socket or on engaging surfaces of the socket with the plug.
- As a result, with this connector device, if the plug is inserted into the socket obliquely with respect to the direction in which the plug should be fitted into the socket, the plug or the socket collides with the corresponding uneven portion, so that vibrations corresponding to the uneven portion can be sensed.
- Further, in the present invention, a plug, which composes a connector together with a socket having a protrusion, is formed with an engaging groove into which the protrusion of the socket falls, when the plug is fitted into the socket, wherein an erroneous fitting preventing portion is formed so as to be deformed or broken by the protrusion of the socket when the plug is erroneously fitted into the socket.
- As a result, in this plug, the socket provided in an electronic device such as a video camera can be obviated from being broken by deforming or breaking the erroneous fitting preventing portion of the plug.
- Further, the present invention provides an electronic device having at least a first connector half of a connector including the first connector half having an engaging groove, and a second connector half provided with a protrusion which falls into the engaging groove when the first connector half is fitted thereinto. In the electronic device, an erroneous fitting preventing portion is formed in the first connector half so as to be deformed or broken by the protrusion of the second connector half when the first and second connector halves are erroneously fitted.
- As a result, in this electronic device, the socket can be obviated from being broken by deforming or breaking the erroneous fitting preventing portion of the first connector half.
- Further, the present invention provides an electronic device having at least one of a plug and a socket of a connector composed of the plug and the socket into which the plug is inserted. In the electronic device, uneven portions are formed on engaging surfaces of the plug with the socket and/or on engaging surfaces of the socket with the plug.
- As a result, in this electronic device, if the plug is inserted into the socket obliquely with respect to the direction in which the plug should be fitted into the socket, the plug or the socket collides with the corresponding uneven portion, so that vibrations corresponding to the uneven portion can be sensed.

- FIG. 9 is a cross-sectional view illustrating the structure of a plug according to another embodiment.
- Preferred embodiments of this invention will be described with reference to the accompanying drawings:
- (1) First Embodiment
- In FIGS. 1A to1C,
numeral 1 shows a plug considered as a first connector half of a first embodiment. Amain body 2 is formed on one side thereof with aninserting protrusion 3. Theinserting protrusion 3 has atop surface 3A having a throughhole 4 at a predetermined position, and abottom surface 3B having arecess 6 as an engaging groove. - Also, the
inserting protrusion 3 is formed inside thereof with a plurality of connectingterminals 5 which extend through themain body 2 and are electrically connected to a cable (not shown) on the other side of themain body 2. - Actually, the
inserting protrusion 3 is composed of ametal cover 3D made of metal such as phosphor bronze, and aresin base 3E made of resin such as LCP. - On the other hand, in FIGS. 2A and 2B,
numeral 10 shows a socket considered as a second connector half corresponding to the plug 1 (FIGS. 1A to 1C). On one side of amain body 11, areceptacle 11A for receiving theplug 1 is opened. Inside thereceptacle 11A, adetent terminal 12 is formed corresponding to the throughhole 4 of theplug 1, and arecess 15 is formed in abottom surface 11B of themain body 11. - In addition to the foregoing components, inside the
receptacle 11A of thesocket 10, a plurality of connectingcontact pins 13 corresponding to the connectingterminals 5 of theplug 1 are formed such that they are covered with a connectingpin holder 14 except for theircontact portions 13A protruding therefrom. - Actually, the
main body 11 is formed of ametal cover 11C made of metal such as steel, and aresin base 11D made of resin such as LCP, PPC or the like. - Thus, as illustrated in FIG. 3, the
recess 6 of theplug 1 is aligned with therecess 15 of thesocket 10, and theplug 1 is fitted into thereceptacle 11A of thesocket 10, causing thetip 12A of thedetent terminal 12 of thesocket 10 to fall into the throughhole 4 of theplug 1, and the respective connectingterminals 5 of theplug 1 to electrically connect to thecorresponding contact portions 13A of the connectingcontact pins 13 of thesocket 10, thus completing aconnector device 20. - In addition to the structure as mentioned, the
connector device 20 is formed with a break absorbing portion 7 (FIG. 1A) as an erroneous insertion preventing feature by adding a notch into a central portion or the like of thetop surface 3A, between the throughhole 4 and thetip 3C, of theinserting protrusion 3 of theplug 1. - In this way, when the
plug 1 is erroneously fitted into thesocket 10 in reverse, the recess 15 of thesocket 10 collides with thebreak absorbing portion 7 of theplug 1, whereby, as illustrated in FIGS. 4A and 4B, thebreak absorbing portion 7 of theplug 1 is broken, and therecess 15 of thesocket 10 runs into oneside 4A of the throughhole 4 extending in parallel with thetip 3C of theinserting protrusion 3 of theplug 1, thereby preventing theplug 1, as remaining in reverse, from being fitted into thesocket 10, and accordingly obviating thesocket 10 from being broken. - In the foregoing structure, the
connector device 20 has abreak absorbing portion 7 formed by cutting a notch into a central portion, between the throughhole 4 and thetip 3C, of the insertingprotrusion 3 of theplug 1. When theplug 1 is fitted into thesocket 10 in reverse, therecess 15 of thesocket 10 collides with thebreak absorbing portion 7 of theplug 1 to cause thebreak absorbing portion 7 to break. In addition, therecess 15 of thesocket 10 runs into the oneside 4A of the throughhole 4 extending in parallel with thetip 3C of the insertingprotrusion 3 of theplug 1, thereby preventing theplug 1, as remaining in reverse, from being fitted into thesocket 10. - According to this
connector device 20, it is therefore possible to obviate thesocket 10 from being broken. - Note that, the
recess 15 of thesocket 10 can be made of tougher material than thebreak absorbing portion 7 of theplug 1. - FIG. 5 is a front view of a video tape recorder (VTR)60 having the aforementioned socket. The
VTR 60 has asocket 60A which is connected to theplug 1 at the left bottom. Note that, the explanation for thesocket 60A of theVTR 60 will be omitted because it has the same construction as theaforementioned socket 10. - Further, in FIG. 6, the
socket 60A of theVTR 60 is connected to anotherelectronic device 62 by acode 61 having aplug 1 and asocket 10 on the both ends thereof. As a result, information can be communicated between theVTR 60 and anotherdevice 62 through the code. Note that, devices each having thesocket 10 can be connected to each other as long as a code has plugs on the both ends thereof. - According to the foregoing structure, since the
break absorbing portion 7 is formed by cutting a notch into a central portion, between the throughhole 4 and thetip 3C, of the insertingprotrusion 3 of theplug 1 of theconnector device 20, when theplug 1 is reversely fitted into thesocket 10, therecess 15 of thesocket 10 collides with thebreak absorbing portion 7 of theplug 1 to cause thebreak absorbing portion 7 to break. In addition, therecess 15 of thesocket 10 runs into the oneside 4A of the throughhole 4 extending in parallel with thetip 3C of the insertingprotrusion 3 of theplug 1, thereby preventing theplug 1, as remaining in reverse, from being fitted into thesocket 10. It is therefore possible to realize theconnector device 20 which can improve the reliability of connection sufficiently for practical use. - (2) Second Embodiment
- In FIG. 7, where parts corresponding to those in FIG. 2A are designated the same reference numerals, numeral30 shows a socket according to a second embodiment, and the socket is constructed similarly to the
socket 10 according to the first embodiment, except for anuneven portion 32 formed on each of inner walls of ametal cover 31C inside areceptacle 31A of amain body 31. - Actually, the
uneven portions 32 are formed, for example, at a pitch of 0.5 to 1 mm and in a depth of 0.3 to 0.5 mm on each of the inner walls of themetal cover 31C inside thereceptacle 31A of themain body 31, as surfaces engaging with theplug 1 of thesocket 30, in parallel with the direction in which theplug 1 is fitted. - With this structure, as illustrated in FIG. 8, where parts corresponding to those in FIG. 3 are designated the same reference numerals, the
plug 1 is fitted into thereceptacle 31A of thesocket 30 with arecess 6 being aligned with arecess 15 of thesocket 30, thereby completing aconnector device 40. - In this event, if the
plug 1 is erroneously inserted obliquely into thereceptacle 31A of thesocket 30, atip 3C of theplug 1 is rubbed with theuneven portion 32 formed on any of the inner walls of thereceptacle 31 of thesocket 30 to make frictional sound. In addition, vibrations resulting from this rubbing are transmitted to the hand, which shows that theplug 1 is not being correctly fitted into thesocket 30. - With the foregoing structure, in the
connector device 40, theuneven portion 32 is formed on each of inner walls of themetal cover 31C within thereceptacle 31A of themain body 31 of thesocket 30, such that if theplug 1 is erroneously inserted obliquely into thereceptacle 31 of thesocket 30, thetip 3C of theplug 1 is rubbed with theuneven portion 32 formed on any of the inner walls of thereceptacle 31 of thesocket 30 to make frictional sound, and vibrations resulting from this rubbing are transmitted to the hand, which is warning of the situation where theplug 1 is not being correctly fitted into thesocket 30. - According to the
connector device 40, it is therefore possible to obviate theplug 1 from being obliquely fitted into thesocket 30. - According to the foregoing structure, the
uneven portion 32 is formed on each of the inner walls of themetal cover 31C inside thereceptacle 31A of the amain body 31 of thesocket 30 of theconnector device 40, such that if theplug 1 is erroneously inserted obliquely into thereceptacle 31 of thesocket 30, thetip 3C of theplug 1 is rubbed with theuneven portion 32 formed on any of the inner walls of thereceptacle 31 of thesocket 30 to make frictional sound, and vibrations resulting from this rubbing are transmitted to the hand, which shows that theplug 1 is not being correctly fitted into thesocket 30.

The position at which the notch is formed can be in any region, not limited to a central portion, as long as the position lies between the throughhole 4 and thetip 3C of thetop surface 3A of the insertingprotrusion 3 of theplug 1. Alternatively, a variety of other methods can be applied to the formation of thebreak absorbing portion 7, provided that the material characteristics are changed by a thermal treatment, a chemical treatment or the like to make only thebreak absorbing portion 7 more susceptible to breakage or deformation. - Also, in the foregoing embodiment, the
uneven portion 32 is formed on each of inner walls of themetal cover 31C, which are engaging surfaces with theplug 1, inside thereceptacle 31A of the amain body 31 of thesocket 30. The present invention, however, is not limited to this formation. For example, as illustrated in FIG. 9,uneven portions 51 can be formed on atop surface 50A and abottom surface 50B of the insertingprotrusion 50 of theplug 1, which are surfaces engaging with thesocket 30. In essence, a variety of other positions can be widely applied to the formation of theuneven portions plug 1 is fitted obliquely into thesocket 30 is showed if caused. - Further, in the foregoing embodiments, the present invention is applied to a video camera. However, the present invention is not limited thereto, but as the
connector devices - As described above, according to the present invention, a connector device has a first connector half having an engaging groove, and a second connector half provided with a protrusion which falls into the engaging groove when the first connector half is fitted thereinto, wherein an erroneous fitting preventing portion is formed in the first connector half so as to be deformed or broken by the protrusion of the second connector half when the first and second connector halves are erroneously fitted. Thus, the socket can be obviated from being broken by deforming or breaking the erroneous fitting preventing portion of the first connector half, consequently making it possible to realize a connector device which can improve the reliability of connection sufficiently for practical use.
- Also, according to the present invention, a connector device has a plug and a socket for receiving the plug, wherein uneven portions are formed on engaging surfaces of the plug with the socket or on engaging surfaces of the socket with the plug. Thus, if the plug is inserted into the socket obliquely with respect to the direction in which the plug should be fitted into the socket, the plug or the socket collides with the corresponding uneven portion, so that vibrations corresponding to the uneven portion can be sensed, thereby making it possible to realize a connector device which can obviate the socket from being broken, and improve the reliability of connection sufficiently for practical use.
- Further, according to the present invention, a plug, which composes a connector together with a socket having a protrusion, is formed with an engaging groove into which the protrusion of the socket falls, when the plug is fitted into the socket, wherein an erroneous fitting preventing portion is formed so as to be deformed or broken by the protrusion of the socket when the plug is erroneously fitted into the socket. Thus, the socket can be obviated from being broken by deforming or breaking the erroneous fitting preventing portion of the plug, consequently making it possible to realize a plug which can improve the reliability of connection sufficiently for practical use.
- Further, according to the present invention, an electronic device has at least a first connector half of a connector including the first connector half having an engaging groove, and a second connector half provided with a protrusion which falls into the engaging groove when the first connector half is fitted thereinto, wherein an erroneous fitting preventing portion is formed in the first connector half so as to be deformed or broken by the protrusion of the second connector half when the first and second connector halves are erroneously fitted. Thus, the socket can be obviated from being broken by deforming or breaking the erroneous fitting preventing portion of the first connector half, consequently making it possible to realize an electronic device which can improve the reliability of connection sufficiently for practical use.
- Furthermore, according to the present invention, an electronic device has at least one of a plug and a socket of a connector composed of the plug and the socket into which the plug is fitted, wherein uneven portions are formed on engaging surfaces of the plug with the socket or on engaging surfaces of the socket with the plug. Therefore, if the plug is inserted into the socket obliquely with respect to the direction in which the plug should be fitted into the socket, the plug or the socket collides with the corresponding uneven portion, so that vibrations corresponding to the uneven portion can be sensed. Consequently, it is possible to obviate the socket from being broken, and realize an electronic device which can improve the reliability of connection sufficiently for practical use.
- While there has been described in connection with the preferred embodiments of the invention, it will be obvious to those skilled in the art that various changes and modifications may be aimed, therefore, to cover in the appended claims all such changes and modifications as fall within the true spirit and scope of the invention.
